PROPANE & OIL TANK ANCHORING SYSTEMS

GENERAL INSTALLATION NOTES

1. Prior to installing the anchors, check for underground utilities. Always use insulated

gloves when turning anchors into the ground to prevent possible electric shock.

2. The anchors and straps shown here are designed to resist the buoyancy forces from an

empty tank fully submerged, and the lateral forces generated from seismic zone 4

activities and 125 MPH EXP “C” winds. Additionally complies to the State of Florida

Building Code, 2001 Edition (Design is per ASCE 7-98 / Wind speeds to 145 MPH /

Importance factor 1.0 / Exposure “C”).

3. Earth auger anchors or concrete anchors shall have a tested minimum pull out value of

4,725 lbs. when used in the soil type that a specific anchor and is designed for (see Soil

Classification Chart).

a. Soil Class 2 and 3 requires auger anchors a minimum of 36” in length.

b. Soil Class 4(a) requires auger anchors a minimum of 48” in length.

c. Soil Class 4(b) requires auger anchors a minimum of 60” in length.

d. For Soil Class 5 call Minute man Products.

4. Use Minute Man THDHLS or 210 JDH anchors in concrete slabs or footers.

CONCRETE STRAP ANCHORS FOR ABOVE GROUND PROPANE TANKS

TANK SIZE NUMBER OF STRAPS VOLUME OF CONCRETE (SLAB)

350 & 500 gallon 2 10 Cubic Feet

1000 gallon 2 20 Cubic Feet

1500 gallon 2 27 Cubic Feet (1 yard)

2000 gallon 3 21 Cubic Feet

2500 gallon 3 27 Cubic Feet (1 yard)

*Calculation formula for determining pre-existing slab or footer volume:

Length x Width x Height (in inches) ÷1728”= Cubic Feet

5. Strap shall be: 1 ¼” x .0.035 Galvanized Steel Strap Zinc Coating meets ASTM D93953

G115.

1. In the event earth auger anchors are precluded from installation, alternate tethering

designs can be submitted for consideration.

2. In all cases, when tanks up to 350 gallons are placed in areas of soil types in notes 3- b.,

c., & d., 2 straps and 4 earth auger anchors are required.
